This release is JS-only, with pre-compressed JS files. Use state.mjs if you only need the processing core, and basic.mjs if a basis for building new visualizers is needed. If you need to target legacy browsers, choose the files starting with xp_.

Documentation is slowly being done.

Known defects

• (low) Held notes in the line style in Cambiare don't style properly if with pitch bend applied. #44

Postponed features

• Baseline MIDI routing (postponed to 0.6)

Additions

Octavia

• Added support to SC display type and SC peak hold type switch SysEx.

• Added dedicated kanas to replace combo kanas for PLG-SG lyrics support.
• Added support for voice element count.
• Added fast parallel async loading for voice mappings.
• Added priority support for bank loading, allowing fast async bank loading without concerns on race condition.
• Added support of Bank A/G selection in X5 extended multi setup. Thanks @JayB1988
• Expanded the program buffer and added channel voice primitives.
• Added generation of offset lookup tables on load for optimization.
• Added a unified method for pushing voice primitives.
• Added subDb support for part voice primitives.
• Added getChPrimitive.
• Added reserved slots for default unset MSB and default unset LSB.

Standard visualizers

• Supported MU channel switching in Octavia QY.

• Added support to all 8 SC strength metre display types and all 4 SC peak hold types in Octavia SC.
• Added a keep value pool in Octavia SC for the lingered peak to match the references.
• Added four overridden system reset prompts in Octavia SC for GM, GS, XG and GM2.

• Added support for SC display types and SC peak hold types in Octavia SC-8850.
• Added practical boot animations to Octavia SC, Octavia NS5R and Octavia SC-8850.
• Added 6 new styles of dashboard-inspired panpot styles in Octavia Cambiare.
• Added 3 new styles of control knob-inspired panpot styles in Octavia Cambiare. Thanks @JayB1988

• Added letter display in non-GS modes for SC-8850.
• Added a new pixel correction profile for Chromium browsers.

Fixes

Octavia

• Fixed a voice fetch bug introduced with subDb.
• Fixed bugs not considering sc the same as gs under certain situations.
• Fixed bugs surrounding getChBm and getVoxBm in shared bitmap fetching methods.
• Fixed bank 0 overrides with LSB bank selection in shared bitmap fetching methods.
• Fixed a bug in EG NRPN CC redirection caused by incorrect maps.
• Fixed a long-standing KORG drum mapping bug caused by incorrect mapping. Thanks @JayB1988
• Corrected the drum NRPN lookup table.

Standard visualizers

• Fixed a bug in Octavia SC when peak hold type is set to 0.
• Moved EFX and bank indicator in Octavia SC-8850 with hardware references. Thanks @Thorndust@discord.com and @MasteredRealm
• Fixed a bug in peak hold type 3 in Octavia SC.
• Let device resets clear the screen dump state in Octavia SC-8850.
• Fixed a bug where unused parts in QY are unable to get highlighted.
• Fixed a bug in counting maximum polyphony with element count in Cambiare.
• Shifted the lines up one pixel in Cambiare.
• Fixed draw calls in Cambiare to match the line position shifts.
• Fixed mispositioned clearRect calls in Cambiare.
• Pan value 0 in SC now shows as L63 instead. Thanks @ValleyBell

Changes

Octavia

• Forced KORG KROSS 2 voices to be in KROSS 2 mode.
• The default MSB for KORG Trinity, Yamaha S90 ES and Yamaha Motif ES has been set to 0, referring to regular GM voices. Thanks @JayB1988
• The default MSB for KORG KROSS 2 has been set to 121, referring to regular GM2 voices. Thanks @JayB1988
• XGworks port selection will now be logged under debug mode.
• ACE (active custom effect) now operates on a per-part basis.
• (N)RPN data commit states are now per-part. Fixes #43.
• getVel switched to bitwise operations for optimization.
• Bank selection range has been expanded from 7 bits to 8 bits.
• Suppress voice changes until program change, meaning that cc0 and cc32 alone no longer cause voice changes. Thanks @JayB1988
• Commit cc0 and cc32 to program buffer on program primitive change.
• Migrated SysEx voice writes to voice buffers.
• cc0 1~55 now select Bank G in 05R/W and X5D(R) mode.
• Mirrored the VL internal bank to VL preset bank 1.

Standard visualizers

• Octavia SC-8850 will refer to capital voice bitmaps with XG plug-in voices, GS voices and SD voices.
• Aligned elements in SC-8850 according to the reference images in manuals.
• The lingered peak value pool in Octavia SC now uses unsigned 16-bit values instead of unsigned 8-bit values for a higher precision.
• Tweaked pixel blurring and peak value falling parameters in Octavia SC to better match the references.
• Channel indexes in Octavia SC are no longer forced to be 2-digits.
• Octavia SC now uses ± when key shift is at 0, with spaces for padding.
• Revamped the generic bitmap loading flow.
• Switched from forEach to fill for buffer initialization in Octavia MU and Octavia SC.
• Switched from the sharp symbol to the normal hash symbol in PRG# in Octavia MU, until a similar glyph could be found.
• Expanded the Octavia SC-8850 canvas to include some labels without changing the 808 by 328 resolution.
• Changed the label colours in Octavia SC-8850.
• Skipped metre rendering for unused parts in QY.
• Manual optimization done in QY resulting in a 54% performance improvement.
• Optimized Octavia Cambiare by 35% via writing texts raw.
• The separator near C~4 (the middle C) is now highlighted in Cambiare.
• A slightly more optimized area clearing flow in SC-8850.
• Raised the canvas text position by one pixel in the pixel correction profile for macOS.
• Temporarily disabled the VL breath noise indicator in Cambiare.

Development related

• Added deno.json for JSR. The file will bork attempts of integrating into the Node.js ecosystem.
• Octavia will now also be published to JSR, aside from Deno Modules.
• File names for XG plug-in voices have been collapsed.
• Added an experimental Standard MIDI File disassembler. Will be rewritten from scratch later.

Miscellaneous

• The older middleware has been deprecated. A newer middleware is being designed, with suggestions from @JayB1988 and @DearHoney_1996@youtube.com.
